preparation example Construction

[0030] d) Preparation of health-preserving water: health-preserving water includes 20-40 parts of gibberellin, 70-90 parts of alcohol with a concentration of 85%, 40000-60000 parts of water, 10-30 parts of rooting powder, and 30-450 parts of water-retaining agent. The components are mixed, stirred and dissolved to obtain the health-preserving water.

[0031] e) Grafting of seedlings: cut off the dead roots of the seedlings after the seedlings have been raised, and then graft them, and put the roots of the seedlings that have been grafted into the water for 2 to 4 minutes, and finally take them to the ground for planting;

[0032] f) Nursery management: After the roots of the seedlings germinate new shoots, wipe off the side shoots of the seedlings, and fertilize them with compound fertilizer after germinating 20cm, once every 13 to 17 days, and untie them after the grafting joints are all healed and lignified.

Embodiment

[0040] A company harvested spikes from the provincial-level designated walnut ear picking garden in Dali City, Yunnan Province on January 18, 2013. Each batch of spikes was dried in the shade for 48 hours before being sealed with wax. The temperature of the wax was 70°C-75°C.

[0041] On January 13, 2013, 1 million walnut seedlings were purchased from Dali, Yunnan, and artificially planted in Nandan. The seedlings were covered with a layer of grass with a thickness of 3 cm, and watered every 10 days.

[0042] On March 8th, the preparation of health-preserving water was carried out. Dissolve 30g of gibberellin in 100ml of alcohol and then add it to 50kg of tap water or mountain spring water. 130 parts of water-retaining agent mixed with 130 parts of gibberellin and rooting powder aqueous solution prepared earlier) and stirred into a viscous shape.

[0043] Grafting began on March 9th: After the seedlings planted in the ground were raised, the dead roots were cut off (the main r...

Abstract

The invention discloses a method for breeding a walnut clone seedling. The method comprises the following processing steps: selecting a land for tree nursery, preparing a rootstock, preparing for scion, preparing a vitality retaining solution, grafting a seedling, managing the land for tree nursery, wherein the vitality retaining solution comprises gibberellin, alcohol, a rooting powder and a water retaining agent, and is prepared by mixing, stirring and dissolving the above ingredients. According to the method disclosed by the invention, the problems of low seedling survival rate, poor health and the like in the traditional method for breeding the walnut clone seedling are solved; the seedling survival rate and seedling yield rate are relatively high; less rootstock and scion are needed; the method can be widely applied to the culture of excellent walnut clone seedlings.

Description

technical field [0001] The invention relates to a method for cultivating seedlings, in particular to a method for cultivating walnut clone seedlings. Background technique [0002] Walnuts include various varieties of the genus Juglans, and are well-known dried fruits with uses such as fruit, oil, wood, landscaping, etc., and have broad development prospects. Walnut seeds reproduce late, and the yield is low and the differences among plants are large. This problem can be solved by using excellent scion breeding clone seedlings. There are generally two methods for cultivating walnut clonal seedlings: one is to sow seeds with lower-priced common walnuts in the nursery, cultivate seedlings for one year, and then graft them with high-quality scions in the spring of the second year. The second is to use common walnut seeds with a lower price. In the greenhouse, when roots and buds grow to a certain length, the scions are directly grafted to the walnut buds, and then planted in th...
